What is the office application that enables you to create documents such as letters and reports is called?

That would be a Word processor, and the most common one people use is Microsoft Word. It’s basically the go-to app when you need to type out letters, reports, essays, or even just quick notes. What’s nice is you can format your text, add images, tables, and make it look professional without too much effort. I personally like it because it saves a lot of time compared to handwriting, plus you can easily edit mistakes.
